Search with windows 7 explorer in my IMdisk ramdrive is showing deleted files along with their previews for non-existing files even after wiping, removing and initializing the ramdrive. Files are going back a few months, I was hoping this would be a bit more secure, is this because the drive is indexed? I though this information would be on the drive itself. Is there a way the securely clean the junk results out of my search which still maintain the index for files I currently work with ?
